This year has been very busy for Jack Black, starting with lending his voice to the lead animated character of "Po" in Paramount Pictures' (Kung Fu Panda. The film has earned more than $626 million worldwide, making it DreamWorks Animation's most successful non-sequel film to date. So it comes as no surprise that DreamWorks has signed Black for the sequel scheduled to release in summer of 2011.

Black was back on top of the box office charts in August for the Paramount release of Tropic Thunder. Directed and written by Ben Stiller, who also starred in the film, Black was joined by the star-studded cast of Robert Downey Jr., Tom Cruise and Matthew McConaughey. The film was #1 in the box office for two straight weeks and has earned over $100 million domestically.

Black recently wrapped filming his next feature film, Year One starring opposite of Michael Cera (Juno). Produced by Judd Apatow (Pineapple Express) and directed by Harold Ramis (Knocked Up), Black plays "Zed" a lazy hunter-gatherer who is banished from his primitive village and set off on an epic journey through the ancient world. This adventure comedy is set to release in June of 2009.
